Distributed Systems Adopt Modular Subsystems Design
|
7.1
A Chinese engineering article describes building a production information-publishing system that sends messages via email, SMS and push, collects post-delivery user behavior, and analyzes engagement to inform decisions. It recommends modular subsystems (api, dispatcher, sender, event-collector, analyser), asynchronous task chaining to limit cascade failures, and reliability/monitoring practices including autoscaling, S3 backups, New Relic, CloudWatch and Splunk.
